Question

12¹/2 percent of the candidates who sat for the examination failed, what percentage of candidates passed? (a) 87.5% (b) 80% 38. In an examination, (c) 79% (d) 76% (e) 69% ​

Answer 1

a. 87.5 %

Explanation:

We have

12 ½ percent = 12.5% = 12.5/100 = 1/8

If 1/8 of the candidates failed, then 7/8 of the candidates passed.

7/8 = 0.875 = 87.5%

Therefore, 87.5% of the candidates passed.

Answer 2

A) 87.5%

Explanation:

Percentage represents a value or ratio expressed in terms of parts per hundred. The percentage symbol "%" indicates that a number or quantity is being expressed as a proportion out of 100.

To determine the percentage of candidates who passed the examination, we can subtract the percentage of candidates who failed from 100%.

Given that 12.5% of the candidates failed the exam, the percentage of candidates who passed can be calculated as:

100% - 12.5% = 87.5%

Therefore, the percentage of candidates who passed the examination is 87.5%.
